Exploring San Francisco's treasures: mashing up public art, social media, and volunteered geographic information to create a dynamic guide

The San Francisco Public Art Map (SFPAM) mashes up disparate sources of data to create a dynamic, comprehensive, and interactive map of public art and landmark buildings in the City of San Francisco. The San Francisco Arts Commission administers publicly funded art and is responsible for over 800 pieces but maps are incomplete or inaccurate. There are hundreds of other art pieces such as murals, street art, and art funded by private organizations not included in the San Francisco Arts Commission dataset. Existing applications focus on one type of art or a narrow selection of installations. No application combines institutional data sets, peer‐reviewed volunteered geographic information, and social media to create a comprehensive view of publicly available art. ❧ The SFPAM consists of a web client and ArcGIS Online maps. The web client uses JavaScript, Dojo, social media application programming interfaces, ArcGIS Server, ArcSDE, REST services, and Microsoft SQL Server technologies. Configuration and development to add functionality to Esri's Public Information Map 2.0 source code transformed a disaster map to an art map. The web application incorporates Stamen Design basemaps to provide a fresh look that complements the art content. ArcGIS Online maps enable users to contribute new art and buildings and view art data on mobile devices through the ArcGIS for Mobile or Collector applications. ❧ There are three levels of curated data: institutional, administrative, and social. Institutional curation consists of datasets provided by institutions that administer or fund public art projects. The administrative level includes reviewed volunteered geographic information. Social curation consists of a dynamic layer of pictures and comments on public art through social media streams such as Flickr, Panoramio, Instagram, and YouTube. The application demonstrates a unique method of combining data sources to provide a public art map for visitors and residents of San Francisco.

旧金山公共艺术地图（San Francisco Public Art Map，缩写SFPAM）整合各类分散数据源，旨在打造一套动态、全面且可交互的旧金山市公共艺术与地标建筑地图。旧金山市艺术委员会（San Francisco Arts Commission）负责统筹公共资助艺术项目，旗下管理超800件艺术作品，但现有相关地图存在信息不全或精准度不足的问题。此外，还有数百件其他艺术作品——包括壁画、街头艺术以及私人机构资助的艺术项目——并未被纳入旧金山市艺术委员会的数据集。现有应用大多仅聚焦单一艺术类型或少量特定艺术装置，尚无一款应用能够整合官方数据集、经过同行评议的志愿地理信息与社交媒体数据，以全面展示可公开获取的艺术资源。

SFPAM由网页客户端与ArcGIS Online地图两大模块构成。该网页客户端采用JavaScript、Dojo、社交媒体应用程序编程接口、ArcGIS Server、ArcSDE、REST服务以及Microsoft SQL Server技术。开发团队对Esri旗下Public Information Map 2.0的源代码进行配置与功能拓展，将一款灾害地图改造为公共艺术地图。这款网页应用集成了Stamen Design底图，以清新的视觉风格适配艺术内容的展示需求。ArcGIS Online地图支持用户通过ArcGIS for Mobile或Collector应用在移动设备上提交新的艺术作品与建筑信息，并查看艺术数据。

该系统设有三级经遴选整理的数据层级：官方机构级、行政级与社交媒体级。官方机构级遴选数据由管理或资助公共艺术项目的机构提供。行政级数据包含经过审核的志愿地理信息。社交媒体级遴选数据则通过Flickr、Panoramio、Instagram以及YouTube等社交媒体平台，动态获取公共艺术作品的相关图片与评论。本应用通过独特的多源数据整合方案，为旧金山的游客与居民提供了全面的公共艺术地图服务。
